Open the flow control valve, make sure the CO

regulator is not open yet. Turn on the feeding pump.

Turn on the Calcium Reactor pump on for 20-30 minutes or until the water inside the chamber runs
clear. Take this opportunity to check for leaks.

Adjust the flow control valve until the drip rate is approximately 2 drips per second.

With the needle valve on the CO
2
regulator opened slightly, slowly open the main valve on the CO
2
tank.

Slowly adjust the needle valve while keeping an eye on the bubble counter. Adjust CO
2
injection rate to 1 bubble every 2 seconds.

Once the reactor is running, you will adjust the flow of CO2 and effluent to match your aquarium’s calcium/alkalinity demand.
Over the course of the next week or two, you will need to fine tune the flow of CO2 and drip rate to match your aquarium’s calcium and alkalinity demands. Every
tank is different and testing your water chemistry is the only way to determine the exact drip rate and CO2 Injection rate that is appropriate for your aquarium
7
As changes to the CO2 bubble rate or the drip rate need time to take effect, we recommend making small changes and allow a few hours (or overnight) for the change to
take effect before making further changes.

To Start Operating
*The cTech will work most efficiently if the internal pH is between 6.5-6.8. For best results, do not set the internal pH lower than 6.4 or higher than 6.9.
Maintenance
It is very easy for the water inlets and outlets to become blocked by the very slow flow
rate, please check the water and air inlets and outlets during regular maintenance.
Check the effluent pH of the water from the water outlet regularly if not using
a controller.
Replace the media annually or as needed.
Replace the filter media of inlet regulary or as needed.

Regular maintenance of the pump will ensure a long life and maximum performance
(recommended every 3 months). You can disassemble the pump through the following steps:

To lower the pH: raise the bubble rate or lower drip rate.
To raise the pH: lower the bubble rate or raise drip rate.
(2) take off the oring on both side
(1) take off the pump
(3) take off the tubes
(4) Take off all the baffles
